用向量法解释立体几何中动与静的变化

On Explaining the Change of Movement and Still in Solid Geometry with Vector

空间向量作为一种工具在立体几何中已得到广泛应用,本文对立体几何中的"动态"问题,进行动与静的转换分析,说明了向量法对于提高空间想象能力、解决动态问题,更显示出其优越性。

As a tool, vector space has been used widely in solid geometry. The paper analyses the shift of movement and still in order to show the advantages of improving the imaginative ability and solving dynamic question with vector.
